    • A sound-amplification apparatus comprises: an acoustic signal source for outputting an acoustic signal; an amplified sound source for receiving the acoustic signal from the acoustic signal source and radiating an amplified sound; a control sound source provided in a vicinity of the amplified sound source for radiating a control sound; and signal processing means for producing a control sound signal by controlling at least one of an amplitude and a phase of the acoustic signal from the acoustic signal source so that an acoustic space having a desired directionality is formed by interference between the amplified sound and the control sound, and providing the control sound signal to the control sound source.
    • 声音放大装置包括:用于输出声信号的声信号源; 放大声源,用于从声信号源接收声信号并放射放大声; 设置在放大声源附近的用于发射控制声音的控制声源; 以及信号处理装置,用于通过控制来自声信号源的声信号的幅度和相位中的至少一个来产生控制声音信号,使得通过放大的声音和控制之间的干扰形成具有期望的方向性的声学空间 声音,并将控制声音信号提供给控制声源。

    • A photosensitive material processing machine for processing a photosensitive material with a processing solution. The machine includes: a processing rack for forming a conveyance path of the photosensitive material in the processing solution; a conveyance roller, which is disposed in the processing rack, for conveying the photosensitive material; a sheet-shaped guide member for slidablly supporting the photosensitive material, in which the guide member is disposed in the processing rack so that the surface faces to the circumferential surface of the conveyance roller; a guide support member, which is disposed at the upper portion or the bottom portion of the processing rack, for supporting the guide member; and a driving means for driving the conveyance roller. In such the machine, the photosensitive material is conveyed by the conveyance roller as the photosensitive material being nipped between the conveyance roller and the guide member.
    • 一种用于用处理溶液处理感光材料的感光材料加工机。 该机器包括:处理架,用于形成处理溶液中感光材料的输送路径; 传送辊,设置在处理架中,用于传送感光材料; 用于滑动地支撑感光材料的片状引导构件,其中引导构件设置在处理架中,使得表面面对传送辊的圆周表面; 引导支撑构件,其设置在处理架的上部或底部,用于支撑引导构件; 以及用于驱动输送辊的驱动装置。 在这样的机器中,当感光材料被夹在输送辊和引导构件之间时,感光材料被输送辊输送。
